“…In addition, Lie conformal algebras have close connections to Hamiltonian formalism in the theory of nonlinear evolution. The structure theory and representation theory of Lie conformal algebras were intensively studied (see, e.g., [1,3,4,6,7,[13][14][15][16][17]). In this paper, we investigate derivation algebras, second cohomology groups and some free modules over conformal algebras associated with loop algebras of the Schrödinger-Virasoro Lie algebra and its extended algebra.…”
